Abstract

PURPOSE:To increase the reading accuracy for an optical character reading device that can read plural types of characters, by changing the types of characters according to the mark signal. CONSTITUTION:The character reading recognition is carried out by giving an optical scan to the character line from left to right. In this case, the heights h1-h5 and center positions x1-x5 of the width direction are detected successively for each character or character type change mark as a preprocess. The heights h1-h5 are successively compared with the hight H' higher than the height H of a character frame 11. When the height h3 larger than H' is detected, whether or not the height indicates a character type change mark 12 is examined. If the mark 12 is decided, the recognized character types of the character recognizing part are changed centering on the mark 12. As a result, the reading accuracy can be greatly increased for a slip on which the figures and ''kana'' (Japanese syllabary) letters which are easily recognized mistakenly are written.
